Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Linearity and monotonicity are dened from code kL to code
2N – 1, where N is the resolution and kL is given by kL = 0.016(2N/VREF),
rounded to the nearest whole code. For VREF = 4.096V and N = 16, kL =
256 and linearity is dened from code 256 to code 65,535.
Note 3: Digital inputs at 0V or VCC.
Note 4: Guaranteed by design and not production tested.
Note 5: Inferred from measurement at code 256 (LTC2606/LTC2606-1),
code 64 (LTC2616/LTC2616-1) or code 16 (LTC2626/LTC2626-1) and at
full-scale.
Note 6: VCC = 5V, VREF = 4.096V. DAC is stepped 1/4-scale to 3/4-scale and
3/4-scale to 1/4-scale. Load is 2k in parallel with 200pF to GND.
Note 7: VCC = 5V, VREF = 4.096V. DAC is stepped ±1LSB between half scale
and half scale – 1. Load is 2k in parallel with 200pF to GND.
Note 8: Maximum VIH = VCC(MAX) + 0.5V
Note 9: CB = capacitance of one bus line in pF.
Note 10: All values refer to VIH(MIN) and VIL(MAX) levels.
Note 11: These specications apply to LTC2606/LTC2606-1, LTC2616/
LTC2616-1, LTC2626/LTC2626-1.
The ● denotes specications which apply over the full operating temperature
range, otherwise specications are at TA = 25°C. (See Figure 1) (Notes 10, 11)
ELECTRICAL CHARACTERISTICS The ● denotes specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. REF = 4.096V (VCC = 5V), REF = 2.048V (VCC = 2.7V), VOUT unloaded,
unless otherwise noted.
